RADIATOR Application filed June 28,

To all whom it may concern:

Be it known that I, PAUL JARAY, a citizen of Austria, residing atFriedrichshafen, Germany, have invented certain new and usefulImprovements in Radiator Coverings, of which the following is aspecification.

My invention refers to the radiators of internal combustion engines onmotor cars and more especially to means for regulating the supply of airto such radiators with a view to preventing an excessive cooling effectfrom taking place, more especially in cold weather. The devices of thiskind 1B hitherto used and having the form of shutters or the likeinvolve considerable draw1 backs inasmuch as they do not allow toexactly regulate the cooling efiect.

The devices according to the present in- 2 vention consist of movablestreamlined shutters which do not offer to the air any resistance worthspeaking of as long as they are kept closed, while on being spread apartthe reduce the passage available for the coo ing air after the manner ofnozzles.

These shutters are preferably disposed either in parallel rows orradially.

In the drawings affixed to the specification and forming part thereoftwo modifica-- 3 tions of a device embodying my invention areillustrated by way of example in a purely diagrammatic manner.

In the drawings Figs. 1 to 3 are. side elevations of a radiator of thenormal type with shutters according to the present invention arranged infront thereof in different positions.

Fig. 4 is a front elevation of a similar radiator wlth shuttersradially-disposed in to front thereof. 1 Fig. 5 is 'alan view drawn to alarger scale, of one 0 these shutters, and

Fig. 6 is a side elevation corresponding to Fig. 5 with the radiatorshown to the rear 46 of the shutters. Referring to Figs. 1' to 3', 1 isthe radiator. The air flowing counter to the direction of travelling, asshown by the arrow 2, encounters a number of streamlined shut- 60 ters 3in two parts hinged together, which when closed, as shown in Fig. 1,offer very little resistance to the air. The shutters are spread apart,against the action of a I claim:

springs 10, by aid of a vertical spindle 11 I disposed in front of theradiator and provided with a crank handle 12, strings 13 fixed .to theshutters being wound up on the spindle and thereby spreading theshutters when the spindle is rotated, whereas the springs will cause theshutters to close again, when the spindle has been released.

In Fig. 2 the shutters 3 are shown spread apart to a certain extent,whereby the passage available for the cooling air is reducedcorrespondingly.

In the position shown in-Fig. 3 where the shutters 3 are fully spreadapart they form a protective covering extending all over the radiatorsurface and preventing the air from entering the radiator altogether.

In-the modification shown in Figs. ii to 6, 5 is the radiator and 6, 6are sectorshaped shutters disposed in front thereof, said shutters beingarranged in pairs hinged together. These shutters may be opened orclosed for instance, by aid of links 7 having their common pivot 8attached to a cable 9. adapted to be operated from the drivers' seat.The pivots 8 of all the links 7 may be connected by a curved rod (notshown), whereby, which is directly connected to the cable 9 is spread,the other will follow this movement. p

I wish it to be understood that I do not desire to be limited to theexact details of construction shown and described for. obviousmodifications will occur to a person skilled in the art.
